It worked just fine until yesterday. Been using Construct 3 for several months now, currently working on a game project. I've been working on Firefox during all this time.
Today I tried to open the project and the screen went red with an error message. Here's a copy-paste of the error:

I tried using Construct 3 on Chrome and it loads projects normally, so worst-case scenario I can work there; but it really sucks that it seems to be not willing to cooperate on Firefox now.
Side note: if I try starting a new project on Firefox it seems to be able to. I don't think it can LOAD it, though.
Any idea what this could possibly be?
